Hi Bryce,

The hotkey itself is functional, as in, if I press it, the integrated display does some flickering thing (like other systems do just before sending the display to external), but external still shows nothing.

xrandr --auto doesn't do anything.

xrandr -q shows this with the external display connected:

Screen 0: minimum 320 x 200, current 2646 x 1024, maximum 8192 x 8192
LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
HDMI2 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)

So it's very weird because the system *is* detecting the display but nothing gets sent to it somehow.
